Designed for maintenance-free operation, it features compact dimensions (5.94 x 2.56 x 3.94 inches) and F1 spade terminals for easy, exact replacement in devices like ONT backup systems and alarm panels. Its shock and vibration resistance ensures durability across temperature extremes, making it a dependable power source for critical backup applications. ## Description ML7-12 - 12 VOLT 7 2 AH SLA BATTERY Review: Perfect Replacement Battery for My ONT - I purchased this battery to replace the backup battery in my home’s ONT, which keeps my fiber internet and phone service running during power outages. My original battery had begun triggering low battery alerts and was no longer holding a proper charge, so I needed a compatible 12V 7Ah sealed lead acid replacement with F1 terminals. This unit is a 12V 7Ah SLA battery with F1 spade terminals, and the dimensions matched my original battery exactly. The terminal size and placement were identical, which made it a true drop in replacement for my ONT. If your existing battery is labeled 12V 7Ah with F1 connectors, this should be fully compatible, but I recommend checking the label on your current battery to confirm before ordering. Removing the old battery was very simple. I opened the ONT battery compartment, disconnected the red and black F1 spade connectors, and lifted the old battery out. Installing this one took just a few minutes. The connectors slid onto the terminals securely, and the battery fit neatly into the compartment without any forcing or adjustment. As soon as I connected it, the ONT recognized the new battery and the low battery warning stopped immediately. The system has been operating normally since installation. While I have not yet had a long power outage to fully test runtime, the battery is charging properly and everything appears stable. For anyone needing a standard 12V 7Ah replacement with F1 terminals for an ONT backup system, this has been a reliable and cost effective solution in my experience. Excellent value for the money. Review: Great battery, using it with our Alarm panel as backup battery - Great battery, using it with our Alarm panel as backup battery. Works, would recommend. Has the small terminal spades, the old battery had the wider ones which needed an adapter, this one fits without the battery terminal adapters from wide to small... ## Features - Ml7-12 Sla Is A 12V 7 2Ah Sealed Lead Acid (Sla) Rechargeable Maintenance Free Battery - Dimensions 5 94 Inches X 2 56 Inches X 3 94 Inches Terminal F1 Listing Is For The Battery Only No Wire Harness Or Mounting Accessories Included - Package Quantity : 1 - Rechargeable Battery That Can Be Mounted In Any Position Resists Shocks And Vibration Long Lasting High Performance In High And Low Temperatures ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K8V30D0 | | Amperage | 7.2 Amps | | Antenna Location | Power Tool | | Battery Capacity | 72 | | Battery Cell Type | Sealed Lead Acid | | Battery Weight | 5 Pounds | | Battery capacity | 72 | | Battery cell composition | Sealed Lead Acid | | Best Sellers Rank | #24,819 in Sporting Goods ( See Top 100 in Sporting Goods ) #2 in Scooter Batteries | | Brand | Mighty Max Battery | | Built-In Media | Battery | | Compatible Phone Models | No Phone Models | | Customer Reviews | 4.5 out of 5 stars 13,372 Reviews | | Item Dimensions | 15.9 x 7 x 10.8 centimeters | | Item Type Name | SLA Battery | | Item Weight | 4.5 Pounds | | Manufacturer | Mighty Max Battery | | Model Name | ML7-12 | | Model Number | ML7-12 | | Number of Batteries | 1 12V batteries required. | | Number of batteries | 1 12V batteries required. | | Recommended uses for product | Power Tool | | Reusability | Rechargeable | | UPC | 860000524902 082045914993 | | Unit Count | 1 Count | | Unit count | 1 Count | | Voltage | 12 Volts | ## Product Details - **Battery capacity:** 72 - **Battery cell composition:** Sealed Lead Acid - **Brand:** Mighty Max Battery - **Number of batteries:** 1 12V batteries required. - **Recommended uses for product:** Power Tool ## Images ![ML7-12 - 12 VOLT 7.2 AH SLA BATTERY - Mighty Max Battery brand product, black - Image 1](https://m.media-amazon.com/images/I/61z9DOmihhL.jpg) ## Questions & Answers **Q: Will this work for my verizon fios backup battery?** A: I use this as a replacement for my FIOS battery backup. My backup is in a wall mounted unit, where newer backups are smaller and use smaller batteries (I think “D” cells). **Q: Is there a car battery charger maintainer to keep this battery charged?** A: AXTRA 12V car battery charger maintainer will work to charge this battery. It has 0.9-amp slow charge (trickle charge and float charge) and 3.6-amp fast charge. AXTRA 3.6-amp car battery charger is great charger to keep battery fully charged. For me to leave the charger connected, charge and maintain the car battery, I would definitely go with AXTRA car battery charger. **Q: Can i use this battery to replace 12v 7ah battery** A: That's what I did. **Q: My charger has 3 12v options, which should i use from this list?: 12v, 12v agm, 12v lithium.** A: Just use 12V. This is a lead acid battery. Your other two settings are for lithium and glass mat. This is neither of those. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Replacement Battery for My ONT *by M***B on 26 February 2026* I purchased this battery to replace the backup battery in my home’s ONT, which keeps my fiber internet and phone service running during power outages.
